Add a portlet to the Admin bar to logout user
In the same way you removed a portlet from the admin bar, you can add your own portlet by editing your sharedlayout.xml.
...
<container id="UILogoutPortlet" template="system:/groovy/portal/webui/container/UIContainer.gtmpl">
<access-permissions>*:/platform/users</access-permissions>
<portlet-application>
<portlet>
<application-ref>platformNavigation</application-ref>
<portlet-ref>UILogoutPortlet</portlet-ref>
</portlet>
<access-permissions>*:/platform/users</access-permissions>
<show-info-bar>false</show-info-bar>
</portlet-application>
</container>
...
Style of portlet container can be changed by editing this css file:
eXoResources/skin/DefaultSkin/portal/webui/component/view/UIToolbarContainer/Stylesheet.css
.UIToolbarContainer .UILogoutPortletTDContainer { float: right; /* orientation=lt */ float: left; /* orientation=rt */ }
